Nokia filed a brief with the U.S. Court of Appeals for the Federal Circuit in Washington earlier this week in an effort to help Apple achieve a permanent injunction of some Samsung phones.

According to Nokia, U.S. District Judge Lucy Koh was wrong in making Apple show "causal nexus" between demand for the iPhone and the patent violations.

Keith Broyles, Nokia's attorney from Alston & Bird, said that Nokia joined the case as an ally for Apple in order to protect patents for future innovative devices.

"Nokia has recently been involved in numerous U.S. patent lawsuits, as both a plaintiff and defendant," Broyles wrote. "Nokia is thus both a significant patent owner that might seek an injunction to protect its patent rights, and a manufacturer in an industry in which patent owners routinely issue threats of injunctions for patent infringement."

This case has been ongoing for some time. Last June, Apple's patent infringement claims against Samsung for its Galaxy Nexus phone led to a preliminary injunction, ruled by Judge Koh. Samsung then appealed this ruling on July 1 in an attempt to lift the temporary ban. The ban stayed.

However, in December, Judge Koh denied Apple's request for a permanent injunction against certain Samsung phones, which sent the case back to appeals court. Now, apparently Nokia wants in on the action.

To be clear, everyone is being ridiculous here. Apple and Nokia are being ridiculous to the extent to which they patent technologies (sympton of a broken system), while Samsung has a decades long history of curruption both in and outside of Korea. Long before this business with Apple, they were in court with RIM over copying the Blackberry.
